Compressional and recovery behaviour of highloft nonwovens.

The compressional and recovery behaviour of highloft nonwovens has been studied with a view to know how the fibre materials used and manufacturing technologies employed drive and dictate this behaviour. The results show significant effects of physical and mechanical properties of fibres on the compressional and recovery behaviour of highlofls. It is also observed that highlofts produced by different bonding technologies show significantly different compressional and recovery behaviour. The experimental results are found in satisfactory agreement with the theoretical results. [ABSTRACT FROM AUTHOR]
